StevenT Posted November 19, 2007 Report Share Posted November 19, 2007 One of the items I check is the maximum circuit breaker size for a unit and check to make sure that the proper size breaker is in the panel. Today I came across a matched set of compressors. The 2 ton unit called for a 40amp HACR and the three ton called for a 15 amp HACR. This seemed quite odd to me, I usually see larger units with larger breakers. As I said, they are identical units, except size. Quote Link to comment Share on other sites More sharing options...
Bain Posted November 19, 2007 Report Share Posted November 19, 2007 How old were the things? It may have something to do with the 13 SEER change. I regularly see newer two-ton units that look big enough to cool a Wal-Mart. The old rule of thumb was that you'd have 10 amps of over-current protection for every ton of capacity.

StevenT Posted November 19, 2007 Author Report Share Posted November 19, 2007 The units are brand new. I'm wondering if it's a typo on the label. I find it odd that the smaller unit calls fo a 40, etc., but I'm even more taken back that calls for more than the larger unit. Quote Link to comment Share on other sites More sharing options...
Jesse Posted November 19, 2007 Report Share Posted November 19, 2007 Call/email the manufacturer. Most respond quickly with good info. Quote Link to comment Share on other sites More sharing options...
